Abstract - The E5 AltBOC signal is a complex and exotic transmission signal used in Galileo satellites to enable the computation of a precise value for the receiver position. Since this signal is relatively new, there is a lot of unexplored terrain regarding this subject namely the receiver architecture that best suits the problem. This work addresses implementation aspects of an E5 AltBOC receiver ready to demodulate data from both bands E5a and E5b together as Dual Sideband (DSB) or separately as Single Sideband (SSB) and compare its results. This work focus its research on the tracking block where a Doppler frequency and code delay must be aligned between the locally generated replica and the received signal to operate properly. The innovating part of this thesis is the implementation of a Dual Sideband receiver that uses complex correlators in its architecture that can process simultaneously the information of both E5a and E5b data and pilot channels. In the results chapter of this document, we present the comparative results between DSB and SSB for various conditions including the variation of the carrier power to noise ratio. <\/p>\n
